I do notice that the majority of Noel players online utilize the hit-and-run playstyle. Then again, I don't see many Noel players on XBL in the first place except for Luna.
I play a very rushdown Noel myself and it works alright for me. The main problem about Noel is that her blockstrings have a lot of holes in it so it's important to be able to read and analyze how they deal with your pressure.
The three methods which players generally use to deal with pressure is DP, mash 2A, or keep on blocking. Characters which have a good DP, like Ragna and Litchi, you should generally avoid pressuring for extended periods of time, especially if they IB. If they mash 2A whenever you try to rush back in you can stuff them with 2D after your blockstring. Alternatively, you can catch them with a frame trap in your blockstring. If they keep on blocking then you can rush back in and continue to pressure them.
Also this may sound obvious, but it's important to mix up your pressure. 214A is imo, one of Noel's best moves and is extremely underrated. You can throw 214A from any normal or drive and it leads to pretty good damage. If you find your opponent blocking your 6B every single time, try throwing out a 214A in there instead.
